Abstract

The invention relates to a self-resetting disc spring-mass runner composite magnetorheological damper, which is mainly composed of a parallel combination of an energy dissipation module and a self-resetting module. Two high-strength screw rods are fixedly arranged on the outer cylinder body, and two mass runners are arranged in the sealing cavity. It can move along the axis direction of the high-strength screw rod while rotating around the high-strength screw rod; the part of the connecting rod in the sealing cavity is sleeved with a permanent magnet ring, a magnetic-conducting ring, and a magnetic-isolating ring, and the sealing cavity is filled with magnetic The rheological fluid; the left and right disc springs are freely sleeved on the connecting rods outside the sealed cavity, and the permanent magnet rings and the right disc springs are respectively sleeved at both ends of the left and right disc springs. end plate. The invention provides certain rigidity and strength and stable energy dissipation capacity for the structure, and has excellent self-resetting function at the same time.

Description

technical field

[0001] The invention relates to a self-resetting disc spring-mass runner composite magnetorheological fluid damper, which belongs to the technical field of vibration reduction and isolation in civil engineering. Background technique

[0002] Earthquake disasters have the characteristics of suddenness, low predictability and strong destructiveness, and are considered to be one of the most serious natural disasters faced by human beings. It will cause great damage to the structure and seriously endanger people's life and property safety. my country is one of the earthquake-prone countries, so it is very important to reduce earthquake damage to various buildings and infrastructure. The current structure mainly resists earthquakes and dissipates seismic energy by improving its own stiffness and strength. When a strong earthquake acts, even if the overall integrity of the structure is maintained, the deformation is too large and some components are severely damag...
